Table 1 Results of the treadmill CMR test in 19 healthy subjects. The heart rate at peak exercise and start of imaging is expressed as %MPHR. The times from end of exercise to start of imaging, from end of exercise to end of function imaging, and from end of exercise to peak myocardial enhancement are shown.
